Labcorp Genetics (formerly Invitae), Labcorp RCV001349691 SCV001544046 uncertain significance GM3 synthase deficiency 2020-06-22 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals with ST3GAL5-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with leucine at codon 160 of the ST3GAL5 protein (p.Pro160Leu). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and leucine.
